Показано, что в этой зоне происходит одновременный нагрев газом потоков кокса, чугуна и шлака, каждый из которых находится в состоянии теплообмена между собой. Причем процессы взаимного теплообмена осуществляются как конвекцией, так и излучением. Конвекция обеспечивает теплообмен между газом и всеми нагреваемыми материалами, а также между шлаком и коксом, поскольку стекающий по коксу шлак частично покрывает его поверхность. Лучистый теплообмен развивается между коксом, чугуном и шлаком. Его интенсивность увеличивается с ростом температуры нагреваемых материалов. Установлено, что взаимный теплообмен между потоками кокса, чугуна и шлака в орошаемой зоне доменной печи оказывает значительное влияние на формирование температурного поля в этой зоне. Для расчета теплообмена в области заплечиков и горна доменной печи необходимы знания о распределении тепловых эффектов химических реакций прямого восстановления железа, кремния и марганца по высоте орошаемой зоны и доли поверхности кокса, покрываемой шлаком.</p></abstract><trans-abstract xml:lang="en"><p>The problem of stationary heat exchange in the blast furnace smelting zone irrigated with melt, considering features of process of a fi ltration of pig-iron and slag through coke nozzle is formulated. It is shown, that in this zone there is a simultaneous heating by gas of streams of coke, pig-iron and slag, each of which is in a heat exchange condition among themselves. The processes of mutual heat exchange are carried out as convection and radiation. Convection provides heat interchange among gas and all the heated up materials, and also between slag and coke as slag fl owing down on coke partially coats its surface. Radiant heat exchange develops between coke, pig-iron and slag. Its intensity increases with the growth of temperature of heated up materials. It is fi xed, that mutual heat exchange among streams of coke, pig-iron and slag in an irrigated zone of a blast furnace makes considerable impact on formation of a temperature fi eld in this zone. The knowledge of thermal eff ects distribution of chemical reactions of direct restoration of iron, silicium and manganese are necessary for calculation of heat interchange in the fi eld of bosh and a blast-furnace well on height of an irrigated zone and a fraction of a surface of the coke, coated with slag.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>доменный процесс</kwd><kwd>теплообмен</kwd><kwd>зона расплава</kwd><kwd>математическое моделирование</kwd><kwd>движение шлака</kwd><kwd>чугуна</kwd><kwd>кокса</kwd></kwd-group><kwd-group xml:lang="en"><kwd>blast-furnace process</kwd><kwd>heat exchange</kwd><kwd>smelting zone</kwd><kwd>mathematical modeling</kwd><kwd>motion of slag</kwd><kwd>pig-iron</kwd><kwd>coke</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mathematical model of blast furnace Progress and Application to New Technology Development / Jun-ichiro Yagi. 6th International congress on the science and technology of ironmaking – ICSTI, 42nd International Meeting on ironmaking and 13th International Symposium on Iron Ore, October 14th to 18th, 2012, Rio de Janeiro, RJ, Brazil.
